about a year before i bought my 99 xj... my nieces boyfriend was staying with my wife and i to help him get on his feet. i have a friend that owns a mom & pop car dealer.
he had an 87 mj longbed. well i had a $600. credit. so we got the truck for him and it even drove home under its own power for 15 miles. so long story short its been almost 3 years. he drives it every day and has done a ****e load of work to it just to make it dependable.
my point is if i had known they were so collectable among all of us; i would have gotten for my self.haha... but he loves it and is greatful he has has it. he was 20 when we got it for him... he was just about in tears when he saw what i was doing to make a deal for him to have it. he thought i was buying it for me until i just handed him the keys and said restore it...she's yours. he damn near made me bubble-up.lol.
sorry. just had a story about an MJ.lol.

Lol. Absolutely not! If I read his thread right, that's what he's thinking though.

You might post again during the day, or bump this thread. You could also go in "ask a question". You might want to get a few more opinions, maybe catch someone who tried it. I happen to like my Renix Btw! (surprise eh?). Good luck.

Renix Jeep C101 Connector Refreshing
The C101 connector on 1987 and 1988 Renix Jeeps was a source of electrical resistance when the vehicles were new. So much so that the factory eliminated this connector in the 1989 and 1990 models. The factory recommended cleaning this connector to insure the proper voltage and ground signals between the ECU and the fuel injection sensors. We can only imagine how this connector has become a larger source of voltage loss and increased resistance over a period of almost 25 years. The C101 connector needs to be cleaned at least once in the lifetime of your vehicle. Chances are it’s never been done before.
Almost every critical signal between the engine sensors, injectors, and the ECU travel the path through the C101.
The C101 is located on the driver’s side firewall above and behind the brake booster. It is held together with a single bolt in it’s center. To get the connectors apart, simply remove the bolt and pull the halves apart. You will find the connector is packed with a black tar like substance which has hardened over time.
Take a pocket screwdriver or the like and scrape out all the tar crap you can. Follow up by spraying out both connector halves with brake cleaner and then swabbing out the remainder of the tar. Repeat this procedure until the tar is totally removed. This may require 3 or more repetitions. Wipe out the connectors after spraying with a soft cloth.
If you have a small pick or dental tool tweak the female connectors on the one side so they grab the pins on the opposite side a bit tighter. Apply a true dielectric grease, not the stuff that came with your brake pads, to the connection and bolt it back together.

so you said it takes about 15 mins to address vs. doing a full swap that will take way to much time... what all would I need to address???

As for the swap, it's easy ,too. Strip the donor block down to a long block. Remove a coolant galley plug on the driver's side of the block so you can install your CTS. Use your intake and exhaust manifolds along with a gasket for the original motor. Use the original flywheel/flexplate and distributor.
